Adjustable panel
Unlike other panels on the market, the FlatMaster can adjust its brightness from 0 to 100%. Forget about sheets of paper between your telescope and the panel. Control the brightness of your panel remotely. Store the brightness per filter and immediately recall the value you need.
The Flatmaster 250L can reach very high brightness levels, so it can easily support short exposures (2-3 seconds at f/7) with 3 nm narrow band image filters.
Manual button
FlatMaster has a small push button that adjusts different gradual brightness levels. In case you want to manually operate the FlatMaster, no problem, just press the push button to control the brightness.
One-cable operation
Only one cable (USB) is needed to power and control your flat display.
Wi-Fi support
The new Flatmaster is Wi-Fi enabled, allowing you to control and monitor the focus remotely from your cell phone.
In addition, it can operate simultaneously with USB or Wi-Fi, providing flexibility and ease of use for astronomers, all from the convenience of your smartphone.
FlatMaster Wi-Fi control panel
When you connect to the FlatMaster Wi-Fi access point, the panel's control interface is automatically activated and ready for immediate use. In addition, you can conveniently access it from any web browser by simply entering "flatmaster.local" in the address bar.
This function is independent of the operating system and works perfectly together with the USB control, offering flexibility and convenience in a wide range of configurations.
FlatMaster is compatible with the most popular image processing programs, such as SGPro, APT Voyager and N.I.N.A.
Sequence Generator Pro (SGPro)
